Haven't used this, but I've seen it and handled it at my LHBS. The ability to harvest through the bottom is useful. The heat-resistance is useful. It can't hold pressure. If it were $60-$70, I'd be interested. But it's $200 for what boils down to a bunch of plastic. Massively overpriced, AFAIC. There's really nothing I could do with this that I can't do with my Fermonsters, which only cost ~$35 each.
